One man has died and at least 130 people have been injured as pro-reform protestors and government supporters clashed in the Jordanian capital Amman.
Prime Minister Maaruf Bakhit criticised the Islamist opposition groups and said they were trying to 'create chaos' and were getting orders from Egypt and Tunisia.
The clashes prompted police to use water cannons to disperse the protestors.
It was the first death since the outbreak of pro-reform protests in Jordan three months ago.
A doctor at the hospital said the man had 'received blows to his chest, and his teeth were broken'.
But police chief Hussein Majali told a news conference that the man 'died of a heart attack'.
'There were no signs of beating on his body,' he said.
There have also been conflicting reports on the number of people injured.
A medical source said 130 people, including a policeman, were injured in the clashes, including two in 'critical condition'.
However, police said in a statement that '60 civilians and 58 members of police, including a sergeant and a captain were injured. All of them were hospitalised'.
'The security forces had to put an end to the gathering after the two sides clashed,' the statement said.
'Attempts by Amman's governor to calm things down through dialogue have failed and provocations and stone-throwing from both sides continued, prompting police intervention.'
An AFP journalist at the scene said police used water cannons to break up clashes between students demanding reforms and government supporters.
The clashes began after around 200 government supporters threw large stones at more than 2,000 young demonstrators from different movements.
